CBL Data Shredder vs east-tec Eraser

CBL Data Shredder is a free utility for erasing hard-drive contents so existing and future software-based recovery tools cannot retrieve them. It overwrites the entire disk with bit patterns, with methods using different numbers of passes. Users can choose a pattern and pass count; the default is one pass of “00”. The program implements a described US Department of Defense 5220.22-M method using three passes with different patterns, and also lists VSITR, Bruce Schneier, Peter Gutmann, and Royal Canadian Mounted Police DSX methods. Its Peter Gutmann implementation makes 35 passes. The Windows version functions exclusively on Windows XP, Vista, 7, 8, and 10. DOS packages are available as a floppy disk maker, a bootable CD-ROM ISO, and a USB flash drive creator; the USB creator requires Windows 7 or later. The free download requires submitting a name and email address, and downloading means agreeing to the licensing conditions. The product warns that modern-drive features may leave some areas inaccessible to the software and vulnerable to hardware-based recovery. Its DSX method alone is not approved for sanitizing classified information, and current standards require physical destruction afterward.

east-tec Eraser is Windows software for erasing files with selectable methods, verification, and erasure reports. Listed methods include DoD 5220.22-M, GOST P50739-95, VSITR, the Bruce Schneier Algorithm, and the Peter Gutmann method. Verification provides a way to check the operation, while reports provide a record of the erasure. The Eraser Plan costs $39.95 a year, billed per year, and includes one year of free updates and support. A 15-day trial is available, but there is no free plan. The product is therefore a paid Windows tool with an annual plan and a file-focused scope. Users can choose among the named algorithms and review the resulting verification and report information.
